java创建并连接到服务器,创建FFmpeg进程以将文件转为 H.264 / H.265编码流格式

以下是Java代码示例，用于创建并连接到服务器，并使用FFmpeg将文件转换为H.264 / H.265编码流格式：

import java.io.BufferedReader;
import java.io.IOException;
import java.io.InputStreamReader;
import java.util.ArrayList;
import java.util.List;

public class FFMpegConverter {
    private static final String HOST = "your_server_ip_address";
    private static final String USERNAME = "your_server_username";
    private static final String PASSWORD = "your_server_password";
    private static final String FFMPEG_PATH = "/usr/local/bin/ffmpeg";
    private static final String INPUT_FILE_PATH = "path_to_input_file";
    private static final String OUTPUT_FILE_PATH = "path_to_output_file";

    public static void main(String[] args) {
        List<String> commands = new ArrayList<>();
        commands.add("ssh");
        commands.add(USERNAME + "@" + HOST);
        commands.add("cd /path/to/ffmpeg/folder && " + FFMPEG_PATH + " -i " + INPUT_FILE_PATH + " -c:v libx264 -c:a aac -f flv " + OUTPUT_FILE_PATH);

        ProcessBuilder pb = new ProcessBuilder(commands);
        pb.redirectErrorStream(true);

        try {
            Process process = pb.start();

            BufferedReader reader = new BufferedReader(new InputStreamReader(process.getInputStream()));
            String line = null;
            while ((line = reader.readLine()) != null) {
                System.out.println(line);
            }

            int exitCode = process.waitFor();
            System.out.println("Exited with error code " + exitCode);

        } catch (IOException e) {
            e.printStackTrace();
        } catch (InterruptedException e) {
            e.printStackTrace();
        }
    }
}

这段代码使用Java的ProcessBuilder类创建了一个SSH进程，连接到远程服务器并执行FFmpeg命令将输入文件转换为H.264 / H.265编码流格式。在这个示例中，输入文件路径和输出文件路径是硬编码的，但是可以根据需要进行更改。请确保将FFmpeg二进制文件放置在正确的路径下，并且具有执行权限。
